With the continuous improvement of consumers' environmental protection needs, water-based coatings have received much attention in the field of home improvement. Compared with the serious pollution of traditional solvent-based paint, water-based paint has the characteristics of "water", so what is the difference between the wooden door painted with water-based paint and the wooden door painted with oil-based paint? Let's have a look!

1. Quality and performance comparison:

1. Hardness:

Due to the advanced water-based synthetic system, the water-based paint can reach the physical index of 2H when the paint film is completely dry; the ordinary polyurethane paint uses the addition of organic curing agent (TDI), so the paint film of ordinary polyester paint is used. The hardness is the highest; while the oil-based paint needs to be painted many times, and the hardness of the paint film is poor.

2. Hand feel:

Fullness: Polyester paint has the best effect on the feel and fullness of the paint film. The water-based paint adopts the technology of thin coating + "virtual texture", and the feel and fullness after painting have been greatly improved. ; And the film feel and fullness of water-based paint are not very good.

3. Wear resistance and yellowing resistance:

The water-based paint adopts advanced film-forming technology, which makes the surface of the paint film hard and wear-resistant, and will not turn white due to collision; it is not easy to yellow, and the paint film remains clear and transparent for years; it has long outdoor durability.

2. Comparison of environmental protection and health:

1. Environmental protection:

Since the water-based paint uses water as the diluting solvent, the ultra-low VOC content (lower than the national mandatory standard of 200mg/L) is a truly non-toxic and tasteless high-tech environmental protection product. Oil-based paints use organic solvents (banana water, day water) as diluents, and their products contain benzene, toluene, xylene and their derivatives, and polyester paints also use curing agents (including TDI), so polyester Lacquer is the most toxic, followed by nitro-lacquer.

2. Flammability:

Water-based paint uses water instead of organic solvents, and its products are safe and non-flammable, which greatly reduces the risk factors and troubles in production and use. The oil-based paint contains benzene, xylene, acetone, solvent gasoline, and Tianna water, which are all highly flammable items.

3. Stimulating smell:

Water-based paints use water instead of organic solvents, and their products will not produce irritating odors when they are painted. The oil-based paint contains organic solvents, which will volatilize into the air during the process of brushing and drying, directly stimulating the human sensory organs.

4. Check-in time after painting:

The water-based paint is non-toxic, tasteless, environmentally friendly and safe; you can move in after painting. As for oil-based paint, since its organic solvent will volatilize harmful gases during the drying process, it is generally not possible to directly move in after painting, and it needs to wait for a period of isolation.
